A home for the books you read. Folio keeps the books you've read, the passages you saved, and the reviews you wrote. All in one place, and all your own. Your library Every book has its place: Reading, On the Shelf, Finished, or Set Aside. Add a title by searching for it or scanning the barcode, and it shows up with its cover. Open Folio and pick up right where you left off. Quotes and notes Found a line worth keeping? Point your camera at the page and Folio pulls the words off it. Note the page, mark who said it, and the passage joins the rest of what you've collected. Snap the line and keep reading. More than stars Rate the prose, the characters, the pacing, or make up your own categories. Write the kind of review that actually sounds like you, not a row of stars and a shrug. Pass a good book Turn a book into a card worth sending, or share a link that drops it straight into a friend's Folio with one tap. The good ones are meant to travel. Privacy first No social feed, no social anxiety. Your books, quotes, notes, and reviews live on your devices and in your own iCloud, synced privately between them. There's no Folio account, and nothing we can see. You decide what to share, if anything at all. Always yours, always safe Your library syncs through your own iCloud, so it's safe even when your phone isn't. Get a new iPhone or reinstall Folio, and everything's right where you left it. Nothing to set up, nothing to remember. Folio is for readers who'd rather keep their reading close and private.
